Industrial Piercing

An industrial piercing is two or more piercings connected by a single barbell. In normal usage it refers to an ear piercing whereby two helix piercings are connected by a single straight (or curved) barbell. This piercing was first popularized (and named) by Erik Dakota in Body Play magazine #4 (1992), where it was pictured and titled, "industrial ear project."

While most industrials are a straight bar connecting two helix piercings, they are also often done vertically (sometimes more than one, becoming an ear cage) or through piercings other than the helix, such as rook to helix piercing or inner or outer conch piercings.
